WINDOW-SCREEN.

.BFECIFICATION forming part of Letters Patent No. 311,827, dated February 3, 1885.

Application filed November 21, 1882. (No modcli To all whom, it may concern:

Be it known that I, J. R. GRAVER, of Lincoln, in the county of Lancaster and State of Nebraska, have invented a new and useful Improvement in WVindowScreens, of which the following is a full, clear, and exact description, reference being bad to the annexed drawings, forming part of this specification.

This invention relates to collapsible win (low-screens; and it cons sts of the novel construction, hereinafter described and claimed, whereby the screen may be swung to one side when it is desired to reach the window.

In the drawings, Figure 1 is a perspective view of a window-frame with my improved screen attached, and Fig. 2 is an elevation of the supporting-frame of the screen.

The screen consists of the supporting frame A, which is formed of a number of bars, B B, hinged together, and the netting C. which is tacked to the frame. The barsB B are preferably six in number, and are so disposedthat two bars B shall be hinged together, end to end, at each side of the frame which they com-- pose, and that the side bars B shall be hinged at their upper and lower ends to the cross- A rectangular frame is thus formed which is to be fitted snugly into the windowframe D, and secured therein by a screw pass ing through the upper cross-bar. It is desi ned that the corner hinges, E, and the side hinges, F, shall be so arranged that the frame A shall be collapsible or capable of being swung to either side, so that the windows may 1 be reached conveniently when it is desired to adjust the sashes or wash the panes of glass. To hold the frame A firmly at the sides,hooks G may be provided at the sides of the windowframe D, which are adapted to engage with staples H on the screen-frame. \Vith this construction a screen is provided which is adapted to be placed on the inside of windows,

where it will not be exposed to storms, and which may be easily swung aside when the windows are to be open or closed without the inconvenience attending the entire removal and replacement of the screen.

I do not broadly claim a collapsible screen frame consisting of hinged parts rigidly connected by hooks, nor a frame having hinged sections which are to be swung aside in order to reach the window,as such frames have been made prior to my invention. Collapsible screen-frames, however, have heretofore been made with a view to folding them into small compass for convenience in transportation. and to secure this object in the most practical manner the side pieces, which are divided into two parts, and provided with hinges for connecting said parts flexibly together, have been adapted to collapse at their centraljoints, either outwardly from the center of the screen or in a direction at rightanglestothetop and bottom pieces. Such a frame, however, is not adapted to collapse when titted ina window, but only when out of the window and for the purpose of transportation. As the side pieces ofmy frame are collapsible inward toward the center of the screen, and the top bar or piece is rigidly secured to the window-frame, while the bottom bar is loose, the screen may hang like a curtain, and be collapsed toward the center from either side in order to reach the window when the side pieces are disengaged from the hooks.

What I claim as my invention is- The collapsible window-screen consisting, essentially, in the side bars, B, formed in two parts, hinges F, connecting the same at their outer sides, as shown, the end bars, B, and hinges E at the inner angle of the side and end bars, substantially as shown and described, whereby when secured in place in a windowframe the side bars may be folded inward to allow the window to be operated.
